Embodiment Construction

[0031] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0032] Such as figure 1 and figure 2 As shown, the rainwater purification, collection and utilization comprehensive system of the overpass bridge of the present invention includes three parts: a cyclone separation module, a high-efficiency purification module and a plastic water storage module. in:

[0033] The cyclone separation module includes two parts, the flush water tank 1 and the cyclone separator 2. The flush water tank 1 stores the runoff from the overpass road surface. When the water level reaches the limit, the plug is opened under the buoyancy of the float 3 and the 4-way cyclone separator is opened. 2 to discharge water; concentrate the rainwater entering the cyclone separator 2, and under the difference of centrifugal force, the solid particles in the rainwater will go down along the inner wall and be discharged from the bottom ...

Abstract

The invention relates to a method and system for comprehensively purifying, collecting and utilizing overpass rainwater. The system disclosed by the invention comprises a rotational flow separation module, a high-efficiency purification module and a plastic water storage module. According to the method, based on the principle of gravity rotational flow sand setting technology and absorption, filtration and purification technology, emission, collection and purification of overhead overpass rainfall runoff are realized, suspended particles and organic and inorganic pollutants are respectively eliminated efficiently; furthermore, water storage and reuse are carried out to form integrated comprehensive technology for collecting and reusing purified rainwater; multiple effects such as fast elimination of rainwater on an overpass, water-saving irrigation of a green belt below an overpass and pollution control of overpass roadway runoff can be achieved simultaneously; and the method and the system for comprehensively purifying, collecting and utilizing overpass rainwater disclosed by the invention have wide application prospect in the fields of municipal construction and non-point source pollution control.

Description

technical field [0001] The invention belongs to the technical field of urban water resource utilization and non-point source pollution control, and particularly relates to a comprehensive method and system for rainwater purification, collection and utilization of overpass bridges. Background technique [0002] The rapid expansion of urban scale has led to a significant increase in the proportion of impervious surfaces, which has seriously hindered the natural hydrological cycle processes such as evaporation and infiltration, and the proportion of surface runoff has increased significantly, resulting in frequent urban waterlogging, water pollution, and a large loss of rainwater resources. question. While the urban overpass system brings convenient traffic, due to the highly concentrated construction of impermeable pavement, it is difficult to quickly discharge the runoff on the pavement when heavy rain falls, often causing water accumulation under the bridge, which can cause ...
